Specification of Letters Patent.

Patented Nov. 17, 1908.

Application led June 27, 1907. Serial No. 381,084.

To all whom it may concern:

Be it known that I, DUNY A. SCHUTT, a citizen of the United States,residing at Peru, in the county of Miami and State of Indiana, haveinvented certain new and useful Improvements in Grain-Drills, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

My invention refers to improvements in grain drills for the purpose ofplanting grain or seed and it has for its object to provide an apparatusof this class which will properly distribute the grain or fertilizer orboth; to provide simple and' efficient means for driving the mechanismfrom one or both of l the supporting` traction wheels, depending` on thedirection of travel; means for simuli taneously lifting the feedingdisks and for l I l l l l l l l throwing the eeding mechanism out ofgear; means for raising and lowering the frame with relation to thesupporting wheels g means `for providing resilient mounting for i t-hedisks and hangers; means for flexibly connecting the tongue and draftgear, and various other features of improvement as shall be more fullyhereinafter described.

The present invention embodies improveil ments in that class ofmechanism set forth in my copending application filed Dec. 6th, 1906,bearing the Serial Number 346663.

Referring to the drawings -Figure 1 is a plan view of the completemachine. Fig. 2 is a rear elevation, portions of the meehanism beingshown in section, the back frame seat, etc., having been removed. Fig. 3is an enlarged end elevation, showing the frame of the machine in itslowermost position and indicating the working position of the disks.Fig. 4t is a vertical sectional detail view on the line IV. IV. of Fig.3. Fig. 5 is a transverse vertical section on the line V. V. of Fig. 1,showing the frame lowered with relation to the supporting axle, thedisks being raised. Fig. 6 is a similar detail view, showing the frameraised with resectional view on the -line VII. VII. of Fig. 6. Fig. 8 isa transverse vertical sec tional view through the middle of the machineon the line VIII. VIII. of Fig. 1. Fig. 9 is an enlarged horizontalsectional view indicated by the line IX. IX. of Fig. 3. Figi() is avertical detail sectional view indicated by the line X. X. of Fig. 8.Figs. 11 and 12 are detail views on an enlarged l scale showing amodified construction or mounting of the disk hangers. Fig. 13 is a.detailed view of one of the lifting levers, not slotted.

The main frame of the machine consists of front and back bars 2, 3 andan intermediate transverse bar 1l, bars 2 and d being secured at thefront and bar 3 being secured at the back, at both sides of the machine,to oppositely disposed flanges 5, 5, of the housing boxes 6.

7 is the main supporting axle of the machine, mounted at each side inthe axle boxes S, said axle having mounted upon it at each end, by hubsf), the supporting traction wheels 10 of usual construction. The wheels10 are provided at the inner ends of their hubs with ratchet drivingmechanism for imparting movement on forward travel of the machine to thefeeding mechanism, as hereinafter described.

Housing boxes 6, with which the bars 2, 3 and L1; are connected, supportthev entire framework of the machine and its superimposed and dependingmechanism, said housings and framework being arranged for veri; ticaladjustment with relation to the axle bearings, to any degree desired andare thus capable of adjustment with relation to the surface of theground.

11 and 12 represent the grain and gra-in boxes respectively, which aremounted transversely of the machine upon suitable end plates or frames13 supported by legs 111 upwardly from the inner sides of forwardiianges 5 of the housings 6, or in any other suitable manner. The grainand fertilizer, or either, are fed by feeding mechanism actuated byshafts 15, 16 respectively, said shafts being preferably separated attheir middle portions, and each section with its feed wheels driven bythe gearing at each outer end.

"he fertilizer feed shafts 16, which may conveniently be square orsplined, are pr0- vided at their ends with longitudinally movable orsliding bevel gears 17 normally held in mesh with driving bevel gears 17by spring 1S and arranged to be depressed backwardly to throw them outof gear by a sleeve 19. Sleeve 19 is mounted on the outer end of shaft16 by a reduced extension Q0 extending through end plate 21, forming apart of or secured to the lower portion of the grain and fertilizer boxplate 13. Sleeve 19 is preferably beveled or coniform as at 9.2,

providing a bearing for the fork-shaped unshipping wedge 23 mountedtransversely across the inner side of plate 21. The wedge 23 is actuatedby lever 24 pivoted at 25 and having a depending' crank extension 26.Likewise grain feed shaft 15 is adapted to be thrown out of gear bymeans of a doo' 27 mounted on shaft 28 provided with a crank arm 29,said. dog 27 being arranged to bear upwardly underneath shaft 30 of thedriving gear 31 employed to transmit motion to the said grain feed shaft15, thus throwing gear 31 out of mesh with gear 17. Shaft 30 and gear 31are normally7 pressed downwardly into operative position by spring cbearing' against shaft 30 and a fixed abut-V ment, it being understoodthat shaft 30 is mounted in slotted bearings.

Motion is imparted to bevel gear 17 and to bevel gear 31 (on shaft 30)simultaneously by driving bevel 17 when said gears' 17 and 31 are inmesh therewith. Driving bevel 17 is mounted at the upper end of thesquare or splined shaft 32 with which slidingly engages the hub 33 ofbevel gear 34 in mesh with driving bevel 35. Said bevel 35 is loosely journ aled on the axle 7 and is provided at the outer end of its hub witha series of ratchet teeth 36 adapted to be engaged, on forward motion ofthe machine, by pawls 3G of the wheel hubs, more clearly shown in F ig.G.

The wheels 10 are j ournaled by their hubs on the outer ends of thestationary axle 7, being free to rotate in either direction, but by thepawl and ratchet teeth construction which have just described, will onlyimpart feeding motion to the gearing' and the grain and fertilizer feedmechanism when running' in a forward direction.

The axle 7 is mounted at each side of the machine in axle boxes S asstated, and the outer portion of each axle box is closed by a removablecap 37 whereby the various parts may be taken apart. The axle box 8 is,as shown, made of considerable length to embrace the axle and isprovided with an extension 38 upon which rests a projecting button orknob 39 of gear whereby said gear is normally maintained in mesh withdriving gear 35. lts hub 33 extends upwardly through the upper bearingportion 40 of the housing 6, having a sliding bearing therein, and saidhub is lengthened as shown and embraces the square shaft 32 by acorresponding squared central socket 41, sufficient space being leftbetween the top of bearing 40 and the lower side of the hub of drivinggear 17 to permit of the necessary vertical play. By this constructionit will be seen that the frame of the machine and housing 6 may bevertically adjusted with relation to the axle boxes 8, while stillmaintaining driving transmission between gear 35 and gear 17 at eachside. For the purpose of effecting said vertical adjustment I employ alever 42 pivoted at 43 to the inner side of housing 6, and at 44 theterminal of lever 42 is slotted and engages a stud fixed to the lowerside of axle box S, the other end of lever 42 being pivoted at 45 to alink 4G which in turn is pivoted at 47 to crank arm 43 mounted on shaft49. Saidy shaft is preferably squared, extending' transversely of themachine at the back through suitable thimble bearings in brackets 50,and is actuated by the operator through a lever 51. Said lever isconnected by a link 52 with a crank 53 mounted on the lower end ofvertical spindle 54 mounted in suitable bearings 55 and provided with anoperating handle lever 56.

57 is a ratchet wheel, locked by a footoperated spring-pressed pawl 53,whereby the position of lever 51 and the relative positions of the axlebox and housings are maintained. It will be understood that suchconstruction is used at both sides of the machine, and that uponoperating' spindle 54, the connections 44 acting as fulcrums, the entireframe of the machine may be raised and lowered by reason of its beingsupported by pivotal connections 43. By this means the adjustment of themachine towards or from the ground level may be accurately regulated.

Referring again to the means for driving the grain and fertilizer feedmechanism, the fertilizer feed mechanism being already apparent, drivengear 31 imparts power through shaft 30 and bevel gear a to bevel gear Zion shaft 15, when the gears are all in mesh. In order to throw out boththe grain and fertilizer feed from the machine the levers 26 and 29 areactuated simultaneously,l or one or the other may be actuated alone bydisconnecting the other, by means of connecting rod or link 59 pivotallyattached at its other end G0 to the crank arm 61 mounted on spindle 62having an operating lever or handle G3 at its upper end. Said spindle 62is, like spindle 54, mounted in bearing 64 at the back of the machineand is also provided with a ratchet wheel 57 and foot-actuated pawl 58,whereby its position may be fixed at all times.

Spindle G2 is designed to perform the double function of throwing outthe grain and fertilizer feeds and of simultaneously lifting thefeeding' disks of the apparatus, and on the other hand of simultaneouslythrowing in the grain and fertilizer feeds and lowering the disks, sothat feeding of the grain or fertilizer, or both, can only be suppliedto the disks when they are in position for operation in the ground.

65 are the feeding' disks j ournaled for rotation upon the hub of thedisk hanger (36 carried at the rear end of drag bar 67 and provided withupwardly extending conduits 68 to which grain or fertilizer, or both,are

supplied by means of flexible tubes 69 from the feeding mechanism, inthe well known manner. The drag bars 67 are pivotally mounted at 70 upona suitable pivotal bearing shaft or support depending below the frontportion of the machine, and all the drag bars, disk hangers, and disksare designed to be raised and lowered simultaneously by the operator.For such purpose 1 provide a rock shaft 71, preferably squared,extending transversely across the machine at its front upper portion,mounted in suitable bearings and provided with a series of downwardlyextending levers 72. Said levers are preferably slotted as at 7 3, andconnected at their outer ends with connecting rods 7 4 which in turn arepivotally connected at with the disk hangers.

76 are a series of pins or rods pivotally connected at 77 with the dragbars 67 and having surrounding pressure springs 78 bearing upwardlyagainst blocks 79 having a sliding engagement with slots 78 by pins SO.By this `construction it will be seen that there is at all timesprovided a resilient cushioning downwardlypressed bearing against theupper side of the drag bars, tending` to positively insert the disksdownwardly into the earth all at the same time, with means for liftingthe disk hangers and disks against the said resilient pressure. Levers72 are also provided with limiting arms 81 adapted to bear upon theupper edge of the bar 4t when the disks are lowered, as shown in Fig. 3,and to be lifted upwardly therefrom when the disks are raised as in Fig.By means of such arms S1 it will be seen th'at the entire strain istaken off of the lifting mechanism and the disks are positivelysupported in position for operation,

Levers 72 and all of the disks are actuated upon rotation of rock shaft71. To accomplish this I employ a lever arm 82 pivotally connected at S3with arm Sel, which arm in turn is connected at its rear end with crank85 on the lower end of spindle 62 and capable of operation like crankThe connecting ends of lever S2 and rod Set are of elbow form whereby tofacilitate the operation and provide suflicient clearance for the otherparts of the mechanism.

By the construction above described it will be. seen that the grain andfertilizer' feeds and the raising and lowering of the disks, arecontrolled from the single spindle 62. Said spindle and spindle 54 are,as shown in Fig. 1, located at one side and the other re spectively ofthe drivers seat S6, so as toV be within easy reach of the operator.

87 is a curved bar or bars extending upwardly and backwardly from themain cross bar 4, connected by brace S8 with back bar 3, and supportingthe drivers seat, said bar 87 having at its forward lower portion up-'wardl'y and inwardly projecting cheeks 89.

90 represents the tongue of the machine supported by bracket arms 91upwardly above the front bar 2 and pivotally supported at 92 upon atransverse bolt connecting the flanges of brackets 91. At its rear endtongue 90 is provided with a strap 93 surrounding a bolt 91 extendingacross from one cheek 89 to the other, and by this construction it willbe seen that considerable vertical play is provided within strap 98whereby the forward end of the tongue may be raised or lowered to aconsiderable extent. This is a feature of great advantage in adjustingthe tongue to the horses and renders the work of drawing the machineeasy.

95 is the double-tree, not mounted on the tongue as is ordinarily thecase, but directly attached to the main frame. The tree 95 is pivotallymounted by king bolt 95 within the upper and lower sides of a clevis 96verw tically pivoted at 97 in block 98 secured by bolt 99 between anupper plate 100 secured to bar 2 and a lower bar 101 extending forwardlyfrom underneath the main bar 4L. By this construction it will be seenthat the power of the draft horses is imparted directly to the main bodyportion of the machine, a feature of advantage contributing to thedurability, tiexibility and ease of operation In Figs 11 and 12 I haveshown a modified construction whereby the raising and lowering of thedisk hangers and disks and also the maintaining of the resilient cushioning pressure is secured by a single mechanism. Upon rock shaft 71 aremounted the levers 72 provided with a slot 73 and the integralsupporting extensions 81 adapted to bear upon the main bar 4. Said baret is located somewhat forwardly in the machine and the mechanism isarranged in reverse of that already designed, it being understood thatthe rock shaft 71l is however actuated by the same lever Connection. Rod76 is pivotally mounted at 102 between cheeks 103 cast integral with thedisk hanger, rod 76 being similarly surrounded by Vcoil spring 7 8bearing downwardly against the washer disk 104 secured by Cotter pin orotherwise to rod 76. At its upper end rod 7 5 passes through and has asliding bearing in block 105 of stem 106 which passes through slot 7Spindle 76 extends upwardly through and beyond the block 104 and isprovided with a limiting nut 107 so located as to bear down on top ofblock 105, when the disk hanger is lifted, as in Fig. 12, but which maybe pushed upwardly above said block more or less owing to the operationon uneven ground. The upper end of stem 76 is threaded for aconsiderable distance whereby the nut may be set to any desired positionto adjust the mechanism to suit the ground etc. An advantage in theslotted construction of lever 72 is that the stem 106 of the liftingblock 105 may, if necessary, slide into the slot, providing ampleclearance and freedom of motion while greatly facilitating the liftingoperation. Thus assulning the stem 107 to have slipped from one endtothe other of the slot, when the lever is operated pin 106 will slidealong in the slot while the wedge-like action of the lever as it islifted will greatly ease the operation. By this construction, I alsoavoid the necessity of the supplemental connecting rod 74 and secure theraising of the disk by the same means, through which the downwardcushioning pressure is exerted. In Fig. 13 I also show a modifiedconstruction of lifting lever wherein the slot is eliminated, theconnecting rod being' pivoted to the lever as at 108, and good resultsmay be had with this arrangement, the construction otherwise being thesame as already described.

The various advantages and improvements of my invention will be fullyappreciated by all those familiar with this class of apparatus. Themachine is unde1 the complete control of the operator; it providesagainst waste of grain or fertilizer; gives a construction capable of anaccurate degree of adjustment to suit all conditions of ground level,providing a well balanced machine, reducing the work of the horses to aminimum, and simplifying the construction in many essential respects.The size, details, design, or other features of the invention may bevaried or changed by the skilled mechanic, and I do not desire 'to belimited to the exact construction shown, as many of these elements maybe altered to suit varying conditions.
